UNITED STATES JAMES LAWRENCE LAW, OF PUNXSUTAWNEY, PENNSYLVANIA.

RECEP'IACLE FOR EXPLOSIVES.

Application filed March 6, 1925. Serial No. 13,542.

To all whom it may concern:

Be it known that I, JAMEs L. Law, a citizen of the United States,residing at Punxsutawney, in the county of Jefferson and State ofPennsylvania, have invented certain new and useful Improvements in aReceptacle for Explosives, of which the following is a specification.

This invention relates to improvements in receptacles which areprincipally adapted to be used for carrying explosives used in miningoperations.

One of the important objects of the present invention is to provide areceptacle of the above mentioned character, wherein means is providedfor receiving and supporting dynamite caps or detonators which are usedin various mining operations, means being provided for spacing saidexplosives from each other in the receptacle.

A further object of the invention is to provide a receptacle of theabove mentioned character which includes a means for receiving dynamitecaps, additional means being provided for accommodating the lead inwires associated with the caps.

A still further object of the invention is to provide a receptacle ofthe above mentioned character wherein a slidable cover is associatedtherewith, means being associated with the receptacle and the cover forlocking the latter in a closed position to prevent the accidentaldisplacement of the explosives from the receptacle.

A still further object is to provide a receptacle of the above mentionedcharacter 7 which is simple in construction, inexpensive,

and furthermore adapted to the purpose for which the same is designated.

Other objects and advantages of this invention will become apparentduring the course of the following description.

In the accompanying drawing forming part of this specification, and inwhich like numerals are employed to designate like parts throughout thesame Figure 1 is a top plan view of the receptacle embodying myinvention with the slidable cover in an open position.

Fig. 2 is a sectional view through the re; ceptacle and the cover, thelatter being shown in a closed position, and

Fig. 3 is a detail perspective view of the block.

In the drawing wherein for the purpose of illustration is shown thepreferred embodiment ofmy invention, the numeral 1 designates areceptacle which is formed of any suitable non-conductive material,preferably wood and is open at its top. The top of the receptacle isprovided with a substantially dovetailed groove 2 for receiving theslidable cover 3.

The outer end portion of the slidable cover 3 is provided with anopening 4, the top portion of the cover around the opening being cutaway as illustrated at 5 to provide a finger hold whereby the cover maybe opened. For the purpose of holding the cover in a locked positionover the open upper end of the receptacle, there is provided in theouter side of the receptacle a spring latch. The latter includes a pin 6which is adapted for vertical sliding movement in a suitable opening 7provided therefor in the side of the receptacle adjacent the open topthereof.

The slidable pin 6 is provided with a longitudinal slot 8 into whichextends the transverse pin in a manner clearly illustrated in Fig. 2.This construction provides a means for limiting a slidable movement ofthe pin. Any suitable resilient means such as is illustrated at 10 isdisposed in the bottom of the opening or recess 7 and engages the bottomof the pin 6 and normally urges the same upwardly so that the upper endof the pin will extend through the opening 4- provided in the cover 3.By depressing the pin (3 against the tension. of the resilient member10, the upper end of the pin may be brought out of engagement with theopeningi so as to facilitate the sliding movement of the cover inorderto uncover the receptacle.

Cooperating with theuppe'r end of the upwardly urged pin 6 is alongitudinally extending groove 11 provided in the bottom face of thecover. This construction provides a means whereby the outward slidingmovement of the cover with respect to the receptacle is limited, itbeing understood of course that the longitudinally extending groove 11communicates at one end with the opening 4;, while its other endterminates at a point adjacent the inner end of the cover in the manneras clearly illustrated in Fig. 2.

The holder for the explosive caps or dynamite comprises a substantiallyrectangular shaped block 12, the latter being adapted to be removablyinserted within the receptacle 1:3 messes l. The block 12 which is alsoformed of the same material as the receptacle 1 is of substantially thesame width as the width of the interior of the receptacle as is clearlyillustrated in Figs. 1 and 2. The block 32 is preferably of suchthickness as to be dis posed intermediate the sides of the receptacleand for further holding the block in the central portion of thereceptacle, there is provided on each of the sides of the block, thelaterally extending rib The ribs are arranged in parallel spacedrelation with respect to each other and extend for substantially thefull length of the block. The outer edges of these ribs cooperate withthe respective sides of the receptacle so that a plurality ofcompartments such as are shown at 15% will be formed in the receptacle,the purpose of which will be iereinafter more fully descriaed.

The block 12 is further provided with a plurality of verticallyextending cylindrical cells or chambers 15, the'same being arranged inparallel spaced relation with respect to each other and extending fromthe top of the block to a point adjacent the bot tom of the same. Anynumber of these cells or chambers may be provided as is desired and thesame provides a means for receiving the explosive caps or dynamite whichis used for various mining operations in the manner well known in theart.

The upper edge of the block 12 is further provided with a series oftransversely e1:- tending notches 16 each of which cooperates with theupper portion of the respective cells or chambers as is clearlyillustrated in the drawing.

When the block 12 is inserted within the receptacle 1, and is arrangedin the manner shown in Fig. l of the drawing, the explosive caps ordetonators may be readily inserted in the several cells or chambers 15.The lead in wires which are associated with the explosive caps which areof great length are folded. The wires will then be received within therespective chambers 14: provided therefor, it being understood that thenotches 16 will accommodate the portions of the wires which areconnected with the explosives. lVhenthe cover 3 is in, a closedposition, there will be no possibility of the explosives falling out.of. their respective cells or chambers and furthermore damage tothe,explosives will be prevented.

It will thus be seen from theforegoing description, that av receptaclefor carrying explosives used in mining operations has been providedwhich is-very. simple. in construction, the parts being so arranged asto assure the safe handling oft-he explosives. By further constructingthe reeeptacleand the component parts thereof of non-conducti vematerial, there will. be no possibility'of the explosives containedtherein becoming accidentally ignited.

While have shown the preferred embodiment of my invention, it is to beunderstood that various changes in the size; shape and arrangement ofparts may be resorted to without departing from the spirit. or scope ofthe appended claim.

Having thus described my invention, what I claim as new-is:-

A device of the class described comprising an open top receptacle, acover therefor adapted for slidable movement with respect to thereceptacle, said: cover having an opening formed in one end-thereof, andprovided with a longitudinally extending groove in the bottom, one endof the. groove communicating with said opening, a block having a seriesof explosive receiving cells formed therein removablysupported withinthe receptacle, and means for locking the cover in a closed positioncomprising-a spring actuated latch arranged: in: one of the sides of thereceptacle adjacent the upper edge thereof, said latch cooperating withthe opening formed in the cover, saidlatch being adapted for cooperationwith the opposite end of the groove formed-in the bot tom of the coverfor limiting the outward movement thereof;

In testimony whereof I: aiiix my signa ture.
